UNITED STATES CHARLES A. FOX, OF NEW YORK, N. Y.

COLLAPSIBLE BOX.

Application filed January To all whom it may concern:

Be it'known that I, CnAnLns'A. Fox, a citizen of the United States,residing at New York city, county of-Ncw York, and State of New York,have invented certain new and useful Improvements in Collapsible Boxes,of which the following is a specification. l i

This invention relates to improvements in receptacles and has particularreference to a collapsible box.

An object of the present invention is to provide an improved box ofsimple and inexpensive construction in which the walls of the sectionsthereof are so formed and vassembled as to reduce to a minimum theamount of material wasted in the construction of the box and to provide.a box which will be adequately reinforced against collapsing when inuse.

Another object is to utilize a portion of the intermediate section ofthe box which is interposed between the top and bottom sections thereofto provide locking elements capable of engaging one of the walls of thebottom section to aid in maintaining the latter walls in operativeposition.

The above and other objects will appear more clearly from the followingdetailed description, when taken in connection with the accompanyingdrawings, which illustrate preferred embodiments of the inven tive idea.

In the drawings- Figure 1 is a perspective view of one form of theinvention with the box in partially closed position;

Figure 2' is a vertical sectional View there through;

Figure 3 is a plan View of the box illustrated in Figure 1, showing thesame in its collapsed position and Figure 4 is a transverse sectionthrough the box taken substantially on the line 4-4 of Figure 2.

Theform of the invention shown in the accompanying drawings isillustrated in connection with what is generally known, as thetelescoping type of box, but it is to be expressly understood that saiddrawings a e used merely for the purpose of illustrating the inventionas a whole and not to define the limits thereof, reference being had tothe appended claims for this purpose. 4 As shown, the box consists ofbottom and 9,1925. Serial No. 1,436..

152 overlapped and secured to the ends of the front wall 10, and a rearwall 13 which likewise has its ends 14 overlapped with the rear ends ofthe side walls 11 and secured thereto by suitable fasteners 14. The sidewalls 11- and ends 14 are scored, as indicated at 15, so'that the frontand rear walls 10 and 13 may be collapsed as illustrated in Figure 3.The bottom'edge of the rear wall 13 is provided throughout its lengthwith a laterally extending reinforcing.

flange 16 which engages the bottom of the section 7 to aid inmaintaining the rear wall 13 in its operative position and preventinginward collapsing of said wall when the box is collapsed.

The top section also includes side walls 17 and a front wall 18 securedtogether and scored in the usual manner so as to permit 1 of the sectionbeing collapsed, as shown in Figure 3, the rear wall of said top sectionbeing formed by the "intermediate section 9 which acts as a furtherreinforcement for the rear wall 13 of the bottom section when the box isclosed. I

In accordance with the present invention it is proposed. to providefurther means for maintaining the Walls of the bottom section of the boxin operative position and for this purpose the ends of the intermediatesection 9, which form continuations of the side walls 11 and 17 of thebottom and top sections, and which are scored, as indicated at 19, topermit of the folding of the sections as indicated in Figures 1 and 2,are

cut to form locking elements or tongues 20 attached to the side walls 11of the bottom section. When setting up the box these tongues are bentinwardly into engagement with the rear wall 13 and the free extremitiesof the tongues are inserted into angular slots 21 formed in said rearwall so as to provide an interlocking engagement between the side walls11 and said rear wall.

It is noted that the fasteners 14- all penetrate each of the side walls11 and ends 14 below the folding lines 15 so that the portion of eachend wall above the folding line and adjacent the locking tongue will beleft unattached. This will permit of a free movement of the tongue in avertical plane when being inserted into its slot 21 Without placing anyundue strain upon the fasteners 14', as said upper portion of the wall11 above the folding line may have a slight outward movement relativetothe end 14 when said tongue is being manipulated priorto being engagedin its slot.

What is claimed is:

1. In a collapsible box, a bottom section including side walls and a.rear wall having its ends overlapping said side walls,'

section, an intermediate section connectingsaid top and bottom sections,and locking elements formed from the material of said intermediatesection and connected to said upper portions of the side walls abovesaid folding lines'and capable of being inter? locked with said rearwall.

2. In a collapsible box, a bottom section including side Walls and arear wall'having its ends overlapping said sidewalls, means to securethe lower portion of each overlap-. ping end to the adjacent side wallwith the upper portion of said end and contiguous portion or said sideWall remaining unattached to perm'it'of a relative outward movement ofthe latter portion of the sidewall, a top section, an intermediatesection connect-.

ing the top and bottom sections, and locking-elements form cd fromthe-material of said. intermediate section andcarried by the upperportions of said side walls andcapnble of being interlocked with saidrear wall; In testimony whereof I have affixed my signature.
